Abstract

The E/sub /spl theta// patterns in the /spl theta/=90/spl deg/ plane of an array of /spl lambda//2 electric dipoles in presence of a circular cylinder are studied using the NEC-basic scattering code (NECBSC2). The results indicate that acceptable antenna patterns can be obtained by symmetrically weighting the amplitude excitation of dipoles with respect to the center element. The numerical technique for obtaining these patterns, and the effects of creeping waves in the azimuth (/spl theta/=90/spl deg/) plane, are discussed.
